Is there anything after death? What is the meaning of life? Are we just a bag of atoms? The scientist Sabine Hossenfelder, born in Frankfurt (Germany) 48 years ago, is convinced that if there is a branch of science capable of finding answers to humanity’s existential questions, it is physics. Specialized in theoretical physics and quantum gravity, Hossenfelder combines her research work with science communication (she is the creator of the YouTube channel Science without the gobbledygook). Her latest book, Existential Physics: A Scientist’s Guide to Life’s Biggest Questions (published in English in 2022, and out in Spanish this year)...

Germany is not the well-functioning, environmentally super-conscious, high-tech nation it used to be. You go to a train station, half the trains are cancelled, the other half is delayed, the escalators are broken, the announcements are barely audible, and in the unlikely event that you can connect to the wifi it’s so slow that by the time the news is streaming it’s become a historical documentary. Or maybe it’s quantum wifi, collapses the moment you touch it

How much energy AI really needs. And why that's not its main problem. | 8:05Sabine Hossenfelder | 1.19M subscribers | 171,326 views | March 25, 2024

My new essay is here: https://nautil.us/what-physicists-hav...We've seen a lot of headlines in the past year about how dangerous AI is and how overblown these fears are . I've found it hard to make sense of this discussion. If only someone could systematically interview experts and figure out what they're worried about. Well, a group of researchers from the UK has done exactly that and just published their results. What they have found is, not very reassuring. Let's have a look.The paper is here: https://ieeexplore.ieee.org/document/...AI experts make predictions for 2040. I was a little surprised. | 6:57Sabine Hossenfelder | 1.13M subscribers...

I got a lot of questions last week about an article in Quanta Magazine about Dark Dimensions. it's about an idea motivated by string theory that combines large extra dimensions with dark matter. I had a look at the paper.The paper is here: https://arxiv.org/abs/2311.05318The article in quanta magazine is here: https://www.quantamagazine.org/...String theory nonsense makes comeback | 8:12Sabine Hossenfelder | 1.13M subscribers | 147,734 views | February 7, 2024

In this week's science news, I talk about a new candidate for a cosmic string, the mysterious shrinking of planet Mercury, a nuclear clock, the first quantum engine, a simulator for human diseases, whether we can find new physics with spinning black holes, AI that wants to help find aliens, how to compute with photons, and of course, the telephone will ring.Could this be the first evidence for string theory? | 18:21Sabine Hossenfelder | 1.03M subscribers | 310,893 views | October 10, 2023

A very brief video because I want to tell you about this story I learned from William Jason Morgan's obituary. It's a lovely story about how the process of scientific discovery sometimes takes unexpected turns.He looked for gravitational waves, but discovered something entirely different | 3:39Sabine Hossenfelder | 1.03M subscribers | 232,486 views | October 19, 2023her YouTube channel

If you've been following my channel for a really long time, you might remember that some years ago I made a video about whether faster-than-light travel is possible. I was trying to explain why the arguments saying it's impossible are inconclusive and we shouldn't throw out the possibility too quickly, but I'm afraid I didn't make my case very well. This video is a second attempt. Hopefully this time it'll come across more clearly!I Think Faster Than Light Travel is Possible. Here's Why. | 23:46Sabine Hossenfelder | 943K subscribers | 1,569,919 views | April 8, 2023
